Description Agostino Sarubbo gentoo-dev 2012-03-12 15:24:34 UTC
From secunia security advisory at $URL:

The vulnerability is caused due to an assertion error when processing certain search results and can be exploited via a LDAP search request with "attrsOnly" set to true (e.g. ldapsearch -A).

Successful exploitation requires a proxy server configured to use both a relay backend and a translucent overlay.

The vulnerability is reported in versions prior to 2.4.30.

Update to version 2.4.30.

  service (assertion failure and daemon exit) via an LDAP search query with
  attrsOnly set to true, which causes empty attributes to be returned.
